Place puff pastry on a sheet of parchment. Scatter the blue cheese, bits of bacon, and torn rosemary needles over it. Top with another sheet of parchment. Use a rolling-pin to press the toppings into pastry, maintaining a fairly square shape.

Remove the top layer of parchment and cut the puff pastry into long strip, ½-3/4 in. wide, using a pizza wheel or very sharp knife. Separate the strips, twist, and place on parchment-lined baking sheets. At this point, you are ready to bake the cheese straws or you can freeze them for a later date.

When you are ready to bake the straws, preheat the oven to 400°. Bake them until they have puffed and turned golden brown, about 12 minutes, rotating halfway through. If you have made them ahead and frozen them, they will take a few extra minutes. Allow to cool slightly and serve.
